Parchment paper, also known asbaking paper, is acellulose-based paper whose material has been processed so as to obtain additional properties such asnon-stickiness, grease resistance, resistance to humidity and heat resistance. It is commonly used inbaking and cooking as a disposable non-stick paper. It isgreaseproof paper that can be used for several different applications, its surface prevents the food from sticking, and also is highly heat-resistant with some brands capable of temperatures up to 420 °F (216 °C).[1] It should not be confused withwaxed paper, which is paper that has been coated withwax.
To get its non-stick properties, baking paper is either treated with a “quilon" (a solution ofchromium(iii) in an acidicalcohol to modify the cellulose) or cellulose coated withsilicone.

A common use is to eliminate the need to greasesheet pans, allowing very rapid turnaround of batches of baked goods with minimal cleanup. Parchment paper is also used to cooken papillote, a technique where food issteamed or cooked within closed pouches made from parchment paper.
Parchment paper can be used in most applications that call forwax paper as a non-stick surface. The reverse is not true, as using wax paper would cause smoke in the oven and would adversely affect flavor.[2]
The non-stick properties can be also achieved by employing acoated paper, onto which a suitablerelease agent—a coating with a low surface energy and the capability to withstand the temperatures involved in thebaking orroasting process—is deposited;silicone (cured with a suitablecatalyst) is frequently used.[citation needed]
Parchment paper also has relevant properties for other industries. In the textile tube industry, an outer layer of parchment confers the necessary resistance to abrasion, heat and oil. In other industries, parchment is used as a processing aid due to its release properties, whether for furniture laminate manufacturing and rubber vulcanization.[citation needed]
In creative forms such asorigami thin uncoated parchment paper is often used for tessellations and complex models.[citation needed]
Parchment paper is composed of cellulosic fibers and therefore is considered compostable both in an industrial setting (EN13432) and at home.[citation needed]
